Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
80 words
An X-ray tube having an anode comprising a ring-shaped disc portion and rotating means extending through the center of said disc portion and connected therewith, said disc portion receiving electrons impinging upon it, said disc portion being provided with outwardly extending recesses connected between the focal point path and axle and which at least penetrate partially through the thickness of the disc and thus the direct connection between the axis of the disc and the electron impinging portion is interrupted.
Claim 2
Dependent Claim
80 words
An X-ray tube having an anode comprising a ring-shaped disc portion and rotating means extending through the center of said disc portion and connected therewith, said disc portion receiving electrons impinging upon it, said disc portion being provided with outwardly extending recesses connected between the focal point path and axle and which at least penetrate partially through the thickness of the disc and thus the direct connection between the axis of the disc and the electron impinging portion is interrupted.
Claim 3
Dependent Claim
16 words
An X-ray tube as described in claim 1, said recesses passing entirely through the disk portion.
Claim 4
Dependent Claim
17 words
An X-ray tube as described in claim 2, said recesses having the form of a sun burst.
Claim 5
Dependent Claim
18 words
An X-ray tube as described in claim 3, said recesses being alternate lateral cuts within said disk portion.
Claim 6
Dependent Claim
26 words
A rotating anode for an X-ray tube, as described in claim 1 a securing ring member carried by said disk having an electron impinging portion thereupon.
Claim 7
Dependent Claim
22 words
A rotating anode as described in claim 5, said recesses extending to the edge of said disk and below said ring member.
Claim 8
Dependent Claim
21 words
A rotating anode as described in claim 6, said disk being made of graphite and said ring being made of tungsten.
Claim 9
Dependent Claim
19 words
A rotating anode as described in claim 7, said disk having a plurality of individual spaced members disposed thereupon.
Claim 10
Dependent Claim
19 words
A rotating anode as described in claim 6, said recesses extending from the top and bottom of said disk.
Claim 11
Dependent Claim
31 words
A rotating anode as described in claim 9, said recesses extending alternately from the top and bottom of the disk and extending through at least half the thickness of the disk.
Claim 12
Dependent Claim
15 words
